depending on the book you use. It does grow on or close to the base of a tree. This one was found under a fallen tree on September 29. I have never found one actually growing "on" a tree.
You are right that morels are wonderful. I usually saute morels in butter, but for the chicken mushroom, I bread it and fry it up like fried chicken. Mmmmmm. Probably not the healthiest way to cook it, but I don't find them often enough to make that an issue.
